I have a sequential file in which there are 50 records. Now
I want to copy all the 50 records in the reverse order into
a new file? The last record in the original file should be
the first record in the new file. How can I do it?

The above soultion works only if records are in the sorted
order.
The below piece of code could be used for records which are
not sorted.
******************************************************
//STEP1 EXEC PGM=ICEMAN
//SYSOUT DD SYSOUT=*
//SORTIN DD DSN=INPUT,
// DISP=SHR
//SORTOUT DD DSN=OUTPUT,
// DISP=(NEW,CATLG,DELETE),
// DCB=(DSORG=PS,RECFM=FB,LRECL=80,BLKSIZE=0),
// DATACLAS=PSFB
//SYSIN DD *
INREC OVERLAY=(81:SEQNUM,8,ZD)
SORT FIELDS=(81,8,ZD,D)
OUTREC BUILD=(1,80)
/*
*********************************************************
Record length of the above file is 80
INREC OVERLAY - places sequence number after 80.
Then it is sorted in descending order of sequence nummber.
OUTREC BUILD - removes sequence number and retains original
record.
